It's late here and I need to turn in, so I could well be incorrect.
But your conclusion (*) seems to imply that Abo's sentence is not true
in L (for some fixed language L). So Abo's sentence is not
universally true. So Abo's sentence is true...

Yes, but not universally true.

I don't think the problem is self-reference ("This sentence is a
sentence" is true), and I don't think grounding "truth" in terms of an
interpretation helps, because that's not the natural-language "truth",
which can talk about all interpretations and all L.

The natural language notion of "truth" is ill-defined. It doesn't
mean *anything*, in general. We have to judge the meaning of statements
involving truth on a case-by-case basis.

But you don't know what "unrestricted true" means. In particular,
you don't know what it means for the Liar sentence to be true.

Sure I do.

I don't think you do.

That is, I understand the sentence "This sentence is not
true,"

Well, how do you understand that sentence?

I claim that it does not. If Nixon said "Every statement Dean said
about Watergate is not true", then the meaning of Nixon's statement
depends on what Dean said. You can't assign any meaning to Nixon's
statement until you know what Dean said.

Well, that's bizarre. Here is a grammatical sentence, and it would
seem prime facie that we know what it means.

But we don't. Maybe you have a different notion of what "means"
means than I do.
